I am running Ubuntu 16.04 and everything is working perfectly.
I have a few drives that I use for archive storage, these drives are completly full now and will never be written to again.
I would like to change the mount options in
/etc/fstab so that they are mounted as read-only at boot.
The drives are encrypted with LUKS and have an ext4 file system.
My current line in
/etc/fstab for the drive in question looks like this:
/dev/disk/by-uuid/68271755-703c-48e6-a935-c1237de6b1a8 /mnt/HDD01 auto nosuid,nodev,nofail,x-gvfs-show 0 0
What do I need to change to make it mount the drive read-only, but leaving everything else as it is?
